Yes, ADO is what I meant.

With the recent object-orientation hype, Windows looks more attractive to
developers than UNIX. Probably ADO adds to it.

I have not tried Zope (it's overkill for our tasks) but I think
Zope must have something similar.

According to some individuals here it makes Python dead snake :-))))

This is clever. Though ADO-like higher-level abstraction could
be useful.

Yes, this could be cool.
